hi,

i have a relatively old GEIP that i need to press into service
for a kind of urgent, temporary application. the GEIP has only
32MB DRAM and 4MB SRAM, though; much less than i would like.

can i remove the GE PA and install it in a VIP4-50 w/ 256MZB DRAM
and 64MB SRAM? in case it helps, here's the output from "show diag":

        EEPROM format version 1
        GEIP controller, HW rev 2.02, board revision C0
        Serial number: 14986859 Part number: 73-2167-05

i vaguely recall, but can't quite get into focus, that there is
something about the GE PA and GEIP that causes them to want to stay
together. the fact that the GE PA has no extraction handle sort of
reinforces this. otoh, i was able to remove the GE PA and install
it into the VIP4-50; the interface was recognized and configurable.

it that doesn't work, does any one know whether i can move the DRAM
from the VIP-4/50 into the GEIP, to get more DRAM into the

thanks in advance for any help/advise,
ken

p.s. we realize the use of the GEIP is somewhat disadvantaged as a
GE port. however, this is only a temp bandage and the total bandwidth
presented to the GEIP will be nore more than 200-250Mbps in either
direction.
